Light Machine Corp. Benchman XTr (retrofit)

I found this schematic, but I still need to figure out where each Hall lead connects in breakout pictured above. Anyone have a VMC 4000 with tool changer?

It has been a long time since I worked on a 4000. If you can give me the PCB numbers in the system, I may be able to help.

Thanks X! I'm trying to reconnect the Hall leads and power connections for the spindle. It looks like the Hall leads went to some sort of junction board on the right hand side of the rear panel:

I've also attached pictures of main board to give you an idea of what PCB I'm working with

Thanks for that advice, Andy. Here's the trouble I'm running into. It looks like there were several slots on the spindle drive board that had multiple wires inserted. Like a wire from the spindle's Hall leads paired with a wire from the main control board. You can see the loose wires from the main board in picture of the spindle driver board posted above. Those aren't the Hall leads. And then there's the two wires from the spindle that each terminate in a two-pin header connector (also pictured above). Not sure what those are. I really need someone with one of these machines to help me out. Thanks.

Do you have the part number of the cable on the left side of the first photo? There should be a label with the part number attached. I have some connection diagrams and can check based on the P/N.

I have attached a photo of another (differrent) installation of that speed control.
(This is not wired exactly like your machine, so DO NOT COPY)
You can see that there are several locations with 2 wires in them.
I have also attached an explanation of the connections.

This should explain the connections from the motor to the speed control as well as the connections (Halls) that go to both the speed control and the control PCBs.

Once you give me the cable #, I should be able to give you more information.

Thanks for posting that picture! Unfortunately I couldn't find any label on the cable we're talking about, just the manufacturer's number;

Pegasus,
The attached file shows how to connect the motor to the speed control.
Pin 1 is the inboard-most location. It is the WHT wire in my previous photo.
The motor connects to pins 8-10 of the big orange connector and to the 3 male spade connections on the speed control.

The hall cells connect to the connector you show on pins: 24, 25, & 26. They are used strictly for determining spindle speed; whether it is turning or not and if it is at speed.

I am also attaching a copy of the schematic for your main control board (with the cuts and jumpers identified).
I drew this back in 1999 to develop a universal control board for next generation machine (Benchman XT).
I believe it is accurate, but please use it as a guide and not as 100% guaranteed fact.

Please let me know what else is needed.

Thank you, X. That it going to help a lot. It might be a week or so before I can get back into the machine but I will let you know how it turns out. Thanks again.
